説明
特徴
LSF-121T s designed for multi-pass groove welds. With nice bead appearance, porosity resistance and good slag removability. High welding efficiency, high toughness at low temperature can be obtained. It produces good impact property and minimum 500 N/mm² tensile strength when used with LSW-EG-F3
アプリケーション
Typical applications include pressure vessels, shipbuilding and general steel structure.
使用上の注意
1. Dry the flux at 350°C for 60 minutes before use.
2. When performing first pass welding, it is recommend to use lower current to prevent cracking.
